   In previous implemention, I swap the buffer every time write operation has finished. If two write operations happen continuously, read-buffer will be not empty at second write operation.
   1. At beginning:
   read-buf[], write-buf[]
   2. first write method finished, swap:
   read-buf[data1], write-buf[]
   3. second write method finished, swap:
   read-buf[data2], write-buf[data1]
   4. read:
   read data2. out of order.
